There is some interesting stuff here, such as blade_length, damage_factor and distance_to_next_piece for the head and length for the handle.
Now i seem to have (that is relevant):
axe head scaling
axe head damage factor
axe head length
axe handle scaling
axe handle length
something about offset or distance to next piece
But i still have no idea how to get from this to the ingame stats of length, speed, cut damage and handling.
